Residential Complex Lighting Upgrade in Castro Urdiales
Background
We propose a project to improve the lighting electrical installation of a residential complex. This project aims to optimize the lighting in the complex’s recreational areas, including gardens, tennis courts, and the pool, to achieve greater energy savings. The complex is located in Castro Urdiales, a coastal town in Cantabria, known for its tourism and proximity to Bilbao. The area comprises 4000m², with an 800m² built area, landscaped lawns, trees, a 12×6 community pool, two 23×8 tennis

ITEM 1: Economic Sectors and Activities in Electricity and Electronics
Firms can be classified according to various criteria. Looking at the economic sector, we can distinguish:
a) The primary sector includes companies involved in obtaining basic goods (raw materials) directly from nature, e.g., agriculture, livestock, fisheries, and forestry.
b) The secondary sector transforms products from the primary sector, e.g., factories.
c) The tertiary or services sector distributes goods and meets needs not

Technical Drawing
Perspective
Cavalier Perspective: Two perpendicular axes create a sense of depth with a third, inclined axis.
Isometric Perspective: Axes are separated by equal angles. Piece measurements are maintained, but angles between principal axes are deformed. Parallel lines are preserved.
Drawing from Known Perspectives
Compositional Methods: Extend parallel to the relevant axis (X for vertical, Z for depth) to obtain the projected figure. Locate surfaces originating from vertices to complete

Power Plants:
Hydroelectric plants leverage the power of water, converting it into electrical energy. There are two main types:
- Central Water Gushing: (Utilizing kinetic energy) Built in locations with strong water currents to drive turbines, these facilities have limited applicability.
- Central Water Flooding: (Utilizing potential energy) Water is stored in a reservoir and used as needed to generate electricity. This type has two models:
- Central Shunt: The river is diverted through a small dam into
Plastics Compounding: A Deep Dive into Polymer Additives
Plastics Compounding and Additives
What is Plastics Compounding?
Plastics compounding involves customizing raw plastic materials using various additives to meet specific color, property, and performance requirements.
Compounding Ingredients for Polymers
Various additives modify base polymers, expanding their applications. Key ingredients include:
- Resins: Act as binders, holding constituents together. Determine molding methods. Resin content in the final product ranges from 30% to 100%.
- Plasticizers:
Thermochemical Treatments, Corrosion, and Engines
Thermochemical Treatments
These treatments aim to enhance hardness, wear resistance, and corrosion resistance.
Cementing
This process involves adding carbon to steel.
Carbonitriding
This process involves adding nitrogen and carbon to steel.
Nitriding
This process involves adding nitrogen to steel.
Corrosion
Corrosion is the progressive deterioration of a material due to an oxidizing agent. It typically occurs in moist environments, while oxidation occurs in hot and dry environments.
Types of Corrosion
